The sign is the one chance a fan has of getting on television to display their clever—and occasionally even poignant—perspective on their team, the opponent or the referees.

Most times, these signs admittedly suck pretty badly. But every so often, a camera crew or photographer will capture an absolutely hilarious sign. On this slideshow, we honor the sage, snarky and sometimes silly signage that has been documented throughout the years.

49. Don't Take His Advice

48. Twins Fans for the Win

The Twins pretty much sucked this year. But as these fans reminded the Dodger faithful when the two teams met in interleague play this June, we're all thankful our teams didn't have to deal with Frank McCourt.

47. Double the Fun

We've got two solid signs going on in this one.

1. Duke...I am your father.

2. To understand this one, you need to understand three things. First, they are known as the Maryland Terrapins, hence the turtle reference. Secondly, I believe that is a picture of Kyle Singler. And finally, the joke comes from his apparent resemblance to this kid.

6. Stadium Intruder

5. Sign Warfare

And that, ladies and gentlemen, is the best retaliatory sign ever. (Not that I'm condoning calling somebody "gay" as an insult—but for a college kid at a basketball game who was more than likely drunk, it's the effort that counts.)

3. Joe Cox Approves This Message

2. San Diego State with Some Real Talk

First off, this San Diego State fan was dressed that way for a reason—to mock BYU when his Aztecs faced them in a basketball game last year, of course. From SignOnSanDiego.com:

“The Show” student section has been scheming for months as the debate has raged over whether a line of decorum should or does exist. A year ago, dozens of students wore short-sleeved white dress shirts, ties and bike helmets to mock Mormon missionaries.

So far as I can tell, BYU is in two different conferences—the West Coast Conference and the Mountain Pacific Sports Federation—along with being independent in football.
